Abstract

Lateral guidance transportation systems include at least one route made up of carrier elements and lateral guidance elements, on which at least one transportation vehicle is guided as the main vehicle, which has device(s) for automatically moving along the route, and to which energy is transmitted by a primary circuit having a contact wire arranged along the route, or in a contactless manner. The main vehicle includes a lifting platform that is able to be driven by a drive, especially, for example, an electric motor or a geared motor, and on which there is at least one satellite vehicle that is also includes a drive, such as, for example, an electric motor or a geared motor, for automatically moving along an additional route, and which is arranged for transporting goods. The route includes a satellite route section for the positioning and parking of the satellite vehicle. The satellite route section is truly alignable, by positioning of the main vehicle along its route, on satellite routes arranged transversely to the latter, these satellite routes being arranged on shelves. Satellite route sections and satellite routes include primary conductors which are supplied with energy in a contactless manner from the main vehicle.

Claims

1-14. -14. (canceled)

15. A lateral guidance transportation system, comprising:

at least one route including carrier elements and lateral guidance elements; and

at least one transportation vehicle arranged as a main vehicle and including a device adapted to automatically move the transportation vehicle along the route, energy transferred to the transportation vehicle one of (a) by a primary circuit having a contact wire arranged along the route and (b) in a contactless manner, the transportation vehicle including a lifting platform driven by a drive, the transportation vehicle including at least one satellite vehicle including a drive automatically movable along an additional route and adapted to transport goods;

wherein the route includes a satellite route section for positioning and parking of the satellite vehicle;

wherein the satellite route section is alignable by positioning the main vehicle on satellite routes arranged transversely to a main vehicle route, the satellite routes arranged on shelves; and

wherein the satellite route section and the satellite routs include primary conductors supplied with energy in a contactless manner from the main vehicle.

16. The transportation system according to claim 15, wherein the drive of the lifting platform is provided with energy in a contactless manner.

17. The transportation system according to claim 15, wherein the drive of the satellite vehicle is supplied with energy in a contactless manner.

18. The transportation system according to claim 15, wherein energy is transferable at at least one place in a contactless manner by the main vehicle to at least one primary conductor of at least one shelf of at least one side aisle.

19. The transportation system according to claim 15, further comprising at least one pick-up adapted to contactlessly transmit energy.

20. The transportation system according to claim 15, wherein the main vehicle includes a power supply unit adapted to feed a primary line provided on the main vehicle inductively coupled to a pick-up connected to a terminal box adapted for impedance compensation and which feeds at least one primary line provided in the satellite route section.

21. The transportation system according to claim 15, wherein the main vehicle includes a primary line inductively coupleable, during alignment, to a pick-up arranged in a floor connected, for impedance compensation, via a terminal box, to at least one primary line arranged in a shelf.

22. The transportation system according to claim 15, wherein the lifting platform includes a primary line inductively coupleable, during an aligning orientation of the main vehicle and a vertical positioning of the lifting platform, to a pick-up provided at the shelf, which is connected via a terminal box to at least one primary line provided in a shelf, for impedance compensation.

23. The transportation system according to claim 15, wherein the main vehicle is adapted to supply current of the primary conductor of the respective shelf.

24. The transportation system according to claim 15, wherein at least one pick-up includes one of (a) a U-shaped ferrite core, (b) a C-shaped ferrite core and (c) an E-shaped ferrite core.

25. The transportation system according to claim 15, wherein at least one pick-up includes a flat winding.

26. The transportation system according to claim 15, wherein at least one pick-up includes a flat winding arranged around a middle leg of an E-shaped ferrite core.

27. The transportation system according to claim 24, wherein legs of the E-shaped ferrite core are shorter than a distance of next nearest lest from one another.

28. The transportation system according to claim 15, wherein the primary line is arranged one of (a) as an outgoing line and a return line and (b) as an outgoing line and an at least partially surrounding profile.

29. The transportation system according to claim 15, wherein at least one of the drives includes at least one of (a) an electric motor and (b) a geared motor.
